I have a corrupted fit file. it was recorded by a 910xt during a full ironman (so it should hold 226km).
Tried fixing using Garmin tool and got to only 144km. Please help.
Not sure if this is helpful, but http://www.dcrainmaker.com/tools may be a source for correcting the problem. A little way down under file modification/correction tools you may find one that works. Good luck!
